Defense contractor takes break from F-35 JSF, finds a way to eliminate 99% of the energy cost of desalination.
Lockheed-Martin has developed a way to craft sheets of carbon a single atom thick, which can filter the salt (and just about anything else) from water with a tiny fraction of the energy required by current processes. "Lockheed officials see other applications for Perforene as well, from dialysis in healthcare to cleaning chemicals from the water used in hydraulic fracturing, or "fracking," of oil and gas wells."

Researchers at MIT and in Korea have developed
a new, efficient desalinization nanotechnology
that could theoretically lead to small, portable units
powered by solar cells or batteries, yet deliver enough potable fresh water from seawater to supply the needs of a family or small village
. As an added bonus, the system would simultaneously remove many contaminants, viruses and bacteria. MIT Press Release

Everything I Want to Do Is Illegal
by Joel Salatin. This Saturday will mark this article's four year anniversary. Frankly, I was mildly surprised not to have found it mentioned before in MeFi. It's a good read about a sad state of affairs; how our government is turning its own people into outlaws, because freedom has been traded in for an illusion of security. ...but then we already knew that. Don't we?
As the Pentagon ousts plans to turn insects into cyber war machines
you'd be forgiven for asking the question: Where does the real digital end
and the faked life begin?
Are we simulating life synthetically
? or just speeding up
an entirely natural process
? Technologically engineered life is here to stay
. Its not far fetched to speculate
may become all there is.

Ever since I became a TiVo addict, I've found myself wanting to use its features in real life, wishing I could rewind & replay moments of random comedy & chaos, usually involving my pugs. Soon, thanks the good folks at Deja View, I will be able to, with the help of a head mounted micro video camera unit
that is always on, recording a 30 second buffer of real time, and up to four hours of manually recordable space for once you activate the record button. The scourge of ephemera will be wiped out in our lifetime.
